About this item

• ILLUMINATION FUNCTION: the test light probe built-in flashlight is bright enough to light up your work area. When the two alligator clamps respectively clamp the positive and negative ends of the battery, the flashlight immediately lights up, which is more convenient for you to test at night or in dark areas.
• MULTIFUNCTIONAL CIRCUIT PROBE TESTER：The power circuit probe tester has multiple functions, such as detection Circuit Polarity, Voltage, Connection, Break, Lighting, Ignition Plug, Sensor Measurement, Grounding Test, Continuity Test, Component Activation and other functions. No additional tools needed to help you reduce car diagnosis time.
• OVERLOAD PROTECTION & BUZZER ALARM: In voltage mode, the Tester will display overvoltage warning when voltage exceeds 76VDC. The LCD will display “OL”, red LED light on. In current mode, If the current is too high, the LCD will display “OL”, buzzer alarm. When the current exceeds 10A, the tester will automatically disconnect to protect the circuit to reduce unnecessary losses. The disconnection time varies with the load current.
• 4 OPERATIONAL MODES: The automotive test light offers 4 operational modes: Voltage, Current, Resistance, and Frequency (Resolution: 0.1V/0.1A). It features a dual clip power supply voltage range of 5-60VDC and a probe capable of testing voltages from 1-75VDC, as well as DC current from 0.1-10A. Typically, the electric test pen defaults to voltage mode; you can effortlessly switch to current mode by pressing the small black round button. It draws power directly from the vehicle's battery, eliminating the need for an additional battery.
• EXTENDED SPRING WIRE & ANTI-LOST PROBE COVER: Compared with the ordinary wire, the automotive light tester comes with high quality spring wire that can stretch up to 196.85 inches, making the maintenance and diagnosis work more portable, convenient and fast. It allows you to test from the front of the car to the rear without constantly searching for a suitable ground. In addition, the integrated design of the anti-loss cover ensures no puncture wounds, no matter where you go will not be lost.
• EASY TO READ: The circuit tester combines an LCD digital backlight display with an LED red/green indicator light design, making it easier to read the voltage and current values of the screen and distinguish between positive and negative electrodes.
